Raspberry Pi 4
Codesys 3.5.20 sp3
Codesyscontrol 4.15.0.0 based on sdk 3.5.21.0

Hi all,

I have found a lot of topics but none of them get me on the right path, therfore i started a new post.

Usually i work with plc based systems and codesys but now im trying to create an project where i read out a serial data stream from an arduino connected by an USB port. in the future this need to be more arduino's but first trying to make it work with one

I had my program working but i needed to update my raspberry pu to the letest version to get the mimo screen working.

Now i tried several rules in the CODESYSControl.cfg and/or CODESYSControl_User.cfg files but i never get the com port opened.
At this moment i have an file CODESYSControl_User.cfg with entry:
[SysCom]
Linux.Devicefile.1=/dev/ttyUSB0

I tested the connection with minicom and the data runs fluently.

Can somebody help me with what could be wrong? the com port states ERROR_UNKNOWN 5004 when i tried to open.
